TEF 1058 Heat Trace Thermostat
Mounting of pipe mounted type (fig. 03)
•
Mount the thermostat junction box either standing or hanging to pipe with pipe straps.
•
Remove dust protection or stopping plugs and install selected gland. Install the drain plug at the lowest
point. Use stopping plugs for unused entries. Only certified cable glands and blinds may be used. Select
gland according to the cable diameter used.
Temperature sensor
The sensor must be strapped in good thermal contact with the pipe or equipment. In addition to general mechan-
ical protection, the sensor must be protected so that the thermal insulation cannot be tapped between the sensor
and the heated surface. The sensor is normally fixed to pipe or object by use of aluminum tape. Other methods
could be thermowells suitable for the application.
Note!
The widened area of the capillary tube, shall be clamped by the cable gland sealing ring. The sealing ring is not
dimensioned for the Ø1,5 mm capillary tube.
Termination
In order to maintain the mode of protection, connect the conductors with special care. The isolation must reach up
to the terminals and do not damage the conductor. Termination of heat cables must be according to cable
specification given by the supplier of these. Tighten all the terminals, also those vacant. Reinstall the lid and tight
bolts firmly with suitable tool by hand force. Over tightening may impair the protection category.
